“Our thoughts and prayers are with the families of these sailors,” Vice Adm. Phil Sawyer, commander of U.S. Seventh Fleet, said in a statement.

“Their service and sacrifice will be lasting in Seventh Fleet and we will continue to stand the watch for them, as they did bravely for all of us.”

The survivors of the crash were listed in good condition, and the cause was under investigation, officials said.

“The entire Navy team is working together to investigate the cause of this mishap and we will remain focused on our mission to operate forward in a safe and professional manner,” Capt. Michael Wosj, the commander of Carrier Air Wing Five, said in the Seventh Fleet’s statement.
